Does intraoperative fluoroscopic 3D imaging provide extra information for fracture surgery?

Area of Science:

• Orthopedic Surgery
• Medical Imaging Technology

Background:

• Conventional 2D fluoroscopy in extremity fracture surgery often misses critical issues like suboptimal implant positioning and joint incongruities.
• Intraoperative 3D-rotational X-ray (3D-RX) offers a potential solution for enhanced visualization during fracture repair.

Purpose of the Study:

• To compare the diagnostic information provided by intraoperative 3D-RX versus conventional 2D imaging for extremity fracture reduction.
• To evaluate the impact of intraoperative 3D-RX on the need for revision surgery in extremity fracture cases.

Main Methods:

• A surgery questionnaire assessed surgeon confidence in fracture reduction using 2D methods versus 3D-RX in 42 distal extremity fractures.
• Postoperative radiological findings were analyzed for 81 patients to determine the need for revision surgery after 3D-RX imaging.

Main Results:

• Intraoperative 3D-RX provided significantly more information regarding screw positioning and fracture reduction rotation than conventional 2D methods (p < 0.005).
• None of the 81 patients who underwent 3D-RX imaging required surgical revision based on postoperative radiological examinations.

Conclusions:

• Intraoperative 3D-RX with the new device offers valuable supplementary information for extremity fracture reduction compared to traditional 2D imaging.
• The use of intraoperative 3D-RX may decrease the incidence of revision surgeries for extremity fractures.
